What makes all this especially frustrating is there is no systemic discrimination against females in the workplace.

One of the leading scholars in this field is Christina Hoff Summers of the American Enterprise Institute. She has dissected the data and demonstrated that there is no pay gap once factors such as occupational choice and work hours are added to the equation. And now she has a must-watch video on the subject from Prager University.

All of her data is very compelling, but the most persuasive part of the video is at the beginning when she asks why profit-seeking businesses don’t fire men and hire women if there really is a wage gap.

Statists might respond that businesses are part of some evil patriarchy and that there’s some sort of oligopolistic conspiracy to forego income in order to oppress females. But if that’s what they really think, why don’t these leftists start their own businesses and take advantage of the supposed pay gap? Not only would they earn large profits, but they would also bankrupt existing firms that ostensibly are engaging in discrimination.

Sounds like a win-win, right?

And if they respond by saying that they don’t happen to have business skills because they chose to study more enlightened topics while in school, then ask them why progressive companies from France or Sweden aren’t entering the American market and earning lots of business?

Let’s close with some wisdom on this issue from one of my colleagues at the Cato Institute. Vanessa Brown Calder cites a considerable amount of data on occupational choice, but also focuses on quality-of-life and family issues.

…women are considerably more likely to absorb more care-taker responsibilities within their families, and these roles demand associated career trade-offs. Sheryl Sandberg’s Lean In describes 43% of highly-qualified women with children as leaving their careers or off-ramping for a period of time. And a recent Harvard Business Review report describes women as being more likely than men to make decisions “to accommodate family responsibilities, such as limiting (work-related) travel, choosing a more flexible job, slowing down the pace of one’s career, making a lateral move, leaving a job, or declining to work toward a promotion.” It’s fair to assume that such interruptions impact long-term wages substantially. In fact, when researchers try to control for these differences, the wage gap virtually disappears. …It’s likely that other, more nuanced but documented differences, like spending fewer hours on paid work per week would explain some of the remaining five percent pay differential.

Normally I’m very happy to work for the Cato Institute, both because it is a principled and effective organization.

But I wondered about my career choices last night because I was stuck with the very unpleasant task of live-tweeting the Democrat presidential debate. Cleaning out septic tanks would have been a more enjoyable way to spend my time.

Of all the crazy things that were discussed (you can see my contemporaneous reactions on my Twitter feed), the Clinton-Sanders-O’Malley support for so-called Paycheck Fairness legislation would be at the top of my list.

Yes, I was irked by the myopic fixation on income inequality, the support for class-warfare taxation, and the reflexive advocacy for more government spending, but messing around with the price system – because of an assertion that women are paid 77 cents for every $1 received by men – is an entirely different level of foolishness.

Here’ssome of what I wrote in 2012, for instance, when discussing proposals to give politicians power over wage levels.

…what’s really at stake is whether we want resources to be allocated by market forces instead of political edicts. This should be a no-brainer. If we look at the failure of central planning in the Soviet Union and elsewhere, a fundamental problem was that government officials – evenassuming intelligence and good intentions– did not have the knowledge needed to make decisions on prices. And in the absence of a functioning price system, resources get misallocated and growth suffers. So you can imagine the potential damage of giving politicians, bureaucrats, and courts the ability to act as central planners for the wage system.

Moreover, the left’s theory is based on the assumption that greedy businesses and investors are deliberately sacrificing profits by choosing to pay men more when they could hire equally qualified women for less money.

Consider, for instance, a report from the Pew Charitable Trusts about initiatives on the state level.

…the California Legislature…sent Democratic Gov. Jerry Brown a “pay equity” bill… California isn’t alone in acting. …the governors of Connecticut, Delaware, Illinois, North Dakota and Oregon have signed equal pay laws this year. New York legislators unanimously passed a bill that Democratic Gov. Andrew Cuomo has indicated he will sign. And Massachusetts has two bills pending. Equal pay bills also were introduced in 21 other states.

The article cited my unflattering remarks on the issue.

…some critics, such as Daniel Mitchell of the Cato Institute, a libertarian think tank in Washington, said that the new legislation would put a “catastrophic burden” on businesses. “The notion that there’s some widespread discrimination in the marketplace, there’s just no real-world evidence for it,” Mitchell said. “They’re trying to give the government widespread authority to make very abstract judgments about the value of a job in the private sector.”

And I’m not the only critic.

Here are some excerpts from a recent column in the Wall Street Journal by Sarah Ketterer.

When it comes to economically foolish laws, California is second to none. A good example is the California Fair Pay Act… Like its national counterpart, it is an aggressive attempt to eradicate a wage gap between men and women that is allegedly due to discrimination in the workplace. But this wage gap is illusory, and the legislation will have unintended consequences, including for women.

She’s right. Policy that is bad when implemented by a state can cause widespread damage if imposed nationally.

Ms. Ketterer elaborates on why the proposal is misguided.

The Bureau of Labor Statistics (BLS) notes that its analysis of wages by gender does “not control for many factors that can be significant in explaining earnings differences.” What factors? Start with hours worked. …Men are significantly more likely than women to work longer hours, according to the BLS. And if we compare only people who work 40 hours a week, BLS data show that women then earn on average 90 cents for every dollar earned by men. Career choice is another factor. …Of the 10 lowest-paying majors—such as “drama and theater arts” and “counseling psychology”—only one, “theology and religious vocations,” is majority male. Conversely, of the 10 highest-paying majors—including “mathematics and computer science” and “petroleum engineering”—only one, “pharmacy sciences and administration,” is majority female. Eight of the remaining nine are more than 70% male. Other factors that account for earnings differences include marriage and children, both of which cause many women to leave the workforce for years.

It’s unclear whether Clinton-Sanders-O’Malley know (or even care) that the number is garbage. But what is clear is that legislation based on this dishonest data could cause massive economic distortions.

Though, to be fair, Ms. Ketterer points out that trial lawyers will enjoy more business.

What California’s Fair Pay Act willdo, however, is make the state, already notorious for regulation and red tape, a more difficult place to do business. Companies must now ensure that every penny of wage differential between the men and women they employ is attributable to bona-fide differences in education, training, experience, quantity or quality of work, and so on. …even attempting to do so will only add to companies’ already substantial regulatory-compliance budgets. Some of these factors—quality of work, for instance—are inevitably subjective, yet trial lawyers will swoop in to turn every conceivable pay difference into a lawsuit.

A bunch of lawsuits would actually be the least-worst outcome.

What scares me far more is pervasive controls on wages, which is what our leftist friends ultimately prefer.
